Answer:

x^15

Step-by-step explanation:

Recall these rules of exponents:

(a^m)^n = a^mn

a^m • a^n = a^(m + n)

(x^6)² • x³ = x^(2 • 6) • x³ = x^12 • x³ = x^(12 + 3) = x^15

Find the value of k

Readme [11.4K]

Answer:

Step-by-step explanation:

A straight line is equal to 180. The line AB is 180 degrees. This means 174 + angle = 180 for the angle between point D and B. It must be 6 degrees. This is the same angle as the angle between point A and C.

Line CD is also straight and equal to 180. On the line are the angles, 4k + 90 + 3k + 6 = 180. Solve for k by combining like terms and then using inverse oeprations.

4k + 90 + 3k + 6 = 180

7k + 96 = 180

7k = 84

k = 12

A survey of 2380 golfers showed that 366 of them are left-handed. Find a point estimate for p, the population proportion of golf

cluponka [151]

Answer:

The point estimate is 366/2380

Step-by-step explanation:

Here. we want to find a point estimate for the number of golfers that are left-handed

To get this, we simply divide the number of left-handed golfers by the number of golfers surveyed

Mathematically, this will be 366/2380

Assume that adults have IQ scores that are normally distributed with a mean of Î¼= 105 and a standard deviation Ï =20 . Find the

MArishka [77]

Answer:

0.68268

Step-by-step explanation:

We solve using z score

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

For x = 85

z = 85 - 105/20

z = -1

Probability value from Z-Table:

P(x = 85) = 0.15866

For x = 125

z = 125 - 105/20

z = 1

Probabilty value from Z-Table:

P(x = 125) = 0.84134

The probability that a randomly selected adult has an IQ between 85 and 125 is calculated as:

P(x = 125) - P(x = 85)

= 0.84134 - 0.15866

= 0.68268
